Fixes several compile errors due to the recent hd64461 I/O base changes.
Signed-off-by: Paul Mundt <lethal@linux-sh.org>

hd64461 is mapped in a fixed location, so the I/O base itself is fairly
meaningless as a configuration item. Additionally, this makes it
impossible to share hd64461 code alongside generic drivers (in the case
of sh_dac_audio), so simply make it commonly defined and permit the
mach_is_foo() logic to work out the proper semantics.

Now with all of the TMU users moved over to the new TMU driver, and the
old TMU driver killed off, the left-over infrastructure can go along
with it.

This patch removes the old TMU driver (CONFIG_SH_TMU/timer-tmu.c)
As replacement, select the sh_tmu driver with CONFIG_SH_TIMER_TMU
and configure timer channel using platform data.
If multiple TMU channels are enabled using platform data, use the
earlytimer parameter on the kernel command line to select channel.
For instance, use "earlytimer=sh_tmu.0" to select the first channel.
To verify which timer is being used, look at printouts or the timer
irq count in /proc/interrupts.

This fixes up the broken I2C offset in 32-bit mode.
The cause is because the board datasheet had a mistake.

There is nothing in these routines that inherently depends on R0 use.
Given that these routines are inlined, it is rather easy to blow up the
compiler by exhausting the spill class when performing a 64-bit swab.
This presently manifests itself as the following:
CC fs/ocfs2/suballoc.o
fs/ocfs2/suballoc.c: In function 'ocfs2_reserve_suballoc_bits':
fs/ocfs2/suballoc.c:638: error: unrecognizable insn:

(nil)))
fs/ocfs2/suballoc.c:638: internal compiler error: in extract_insn, at recog.c:1991
This patch switches over to using an arbitrarily assigned register instead.
While the same issue does not exist in the SH-5 case, there is likewise no harm
in having an alternate register used for the byterev/shari pair.

Presently this is special-cased for early initialization. While there are
situations where these static early initializations are still necessary,
with minor changes it is possible to use this for the regular ioremap
implementation as well. This allows us to kill off the special-casing for
the remap completely and to start tidying up all of the SH-5
special-casing in drivers.

Now that the stragglers (MTU2/CMT/etc.) have been rewritten and we are
selecting both GENERIC_TIME and GENERIC_CLOCKEVENTS, the get_offset()
timer op is completely unused. As a result, we are now able to kill off
the ARCH_USES_GETTIMEOFFSET references.

All 32-bit SuperH processors currently go through __ioremap_mode()
and check for IO_TRAPPED and directly mapped segments. With this
patch we simplify the MMU less case with a pass through version of
__ioremap_mode() which just returns the physical address.
The effects of this is change are:
- fix non-MMU ioremap() of high address hardware blocks (sh7203 CMT)
- make sure IO_TRAPPED is not selected

syscall_nr is presently defined as unsigned in the SH-5 pt_regs,
while the syscall restarting code wants it to be signed. Fix this

This consolidates the pci_iomap() definitions and reworks how the I/O
port base is handled. PCI channels can register their own I/O map base,
or if none is provided, the system-wide generic I/O base is used instead.
Functionally nothing changes, while this allows us to kill off lots of
I/O address special casing and lookups.
